The auger seotion fl includes a shaft i5 :similartoi the shatt I I2 and isliprovided "with a "flight 431 by .which' grai'n is movedto'ward the "inlet or 'bootzend of the elevator. .1 V I Provided "on" the side portion 2116f the "housing at-the end oopositeithe bearingbosse's fil isa hearing -boss "4"! that is' adapted to "contain fan an tifriction bearing 48 journalling one end of a shaft 49, the-opposite end of which is journalledin a bearing 59 that is mounted on a bracket 5! that projects from the side of the tubular casing section 4, as best shown in Fig. 6. The shaft 49 projects into the compartment 38 and mounts a sprocket 52. Operating over the sprocket 52 and over a sprocket 53 on the shaft [2 is a chain 54 whereby the main conveyor shaft I2 is adapted to be operated from the shaft 49 as later described.

Slidable on the end of the tubular section and within the space under the rods 29 and 2| is a sleeve 55 that is adapted to be moved to and from the chain housing to vary the size of the inlet; the sleeve being manipulated by a rod 56 that is fixed to the sleeve and slidably mounted in a bearing 51 on the band l5. The free end of the rod terminates in a lateral end 58 to facilitate manipulation thereof.

The tubular casing thus described is mounted on a truck 59 which includes a frame 69 having angle members 6| and 62 spaced apart at their rear ends and which converge forwardly under the tubular casing to connect therewith by brackets 63 as best shown in Figs. 1 and 2. The rear ends of th angle members are connected by a cross bar 64, on the ends of which are journalled ground wheels'65 and 66. Supported on the cross bar 64 and extending upwardly therefrom near the mid portion is a post 61 having a yoke-shaped seat 68 to seat the tubular housing. When the device is to be transported, the tubular casing is retained in the seat by a clamp 69 that extends across the top thereof and has its ends secured to the seat by fastening devices such as bolts 19, however, when it is necessary to raise the tubular housing to a higher position, the retaining clamp is removed as shown in Fig. 2.

Pivotally connected with the ends of the cross member 64 are upwardly and rearwardly diverging angle members H and 12 which are interconnected at their converging ends by a spoollike roller 13 that is journalled on a cross shaft 14 mounted in ears 15 carried by the ends of the members H and 12.

inspection of Figs. 1 and 2.

In order to raise and lower the prop, the members H and 12 are interconnected by a shaft 19 mounting a pulley 89. Operating over the pulley 80 is a cable 8| having one end attached to the forward end of the track 16 by a hook-like bracket 82. The other end of the cable extends forwardly and is wound on a winding drum 83 that is pivotally rotatable on a shaft 84 suspended by arms 85 and 86 from a clamping band 81 that encircles the tubular housing section 4. The shaft 84 includes a crank 88 on one end having a handle 89 by which the drum may be rotated to wind the cable thereon. Winding of the cable on the drum raises the gin pole and causes the spool-likeroller 13 to run on the track 16 and raise the tubular housing, for example, from the position shown in Fig. 1 to the position shown in Fig. 2. When the tubular housing is in desired elevation, the

handle 89 of the crank is engaged with the hook 90 to retain the tubular housing in'adjusted position.

Mounted on the rear ends of the angle members Fixed to the underside of the tubular housing section 3 is a channel-shaped 4 60 forwardly of the cross bar 64 are rods 9| and 92 mounting a motor unit such as an internal combustion engine 93, the engine having a power shaft 94 mounting a pulley 95. Carried on a bracket 96 that is attached to the bars 9! and 92 laterally of the motor shaft is a post 91 carrying a bearing 98 mounting the rear end of a countershaft 99. Fixed to the countershaft on the rearwardly projecting end thereof is a pulley I98 that is adapted to be driven by the motor pulley 95 through a belt NH. The forward end of the shaft is journalled in a bracket-like post I02 that is also carried between the member 50 and which mounts a bearing I03 through which the shaft extends. The forward end of the shaft is connected with the shaft 49 by a universal joint [94 to allow for change in angularity between the respective shafts upon angular adjustment of the tubular housing of the elevator.

Assuming that the elevator is constructed and assembled as described, it is adapted for ready transport to any location where it may be used for lifting grain, for example, from a pile into a truck bed as shown in Fig. 1. For this use, the tubular housing may. remain in the seat 10 as the elevator can tilt on the wheels 59 to allow proper elevation of the discharge end over the bed of a truck as shown in Fig. 1. When the motor is in operation the pulley thereof operates the belt 95 and pulley 91 to turn the shaft 99 and operate the shaft 49 through the universal joint I94 to drive the sprocket 52. The sprocket 52 drives the sprocket 53 through the chain 54 to turn the main conveyor shaft l2 and cause rotation of the auger within the tubular housing. With the adjusting sleeve 55 retracted and the exposed end of the auger resting upon the pile of material, the material is moved into the open end of the tubular housing and upwardly therethrough for discharge through the support 9 into the bed of the truck.

If the material is to be moved to a higher elevation as, for example, into a grain bin as shown in Fig. 2, the fastening devices 1 are removed and the crank handle 89 is disengaged from the hook 99. The winding drum is then rotated by the crank 88 to wind up the cable and effect upward and forward pivotal movement of the prop. The spool-like roller carried thereby will roll downwardly along the track which causes upward movement of the conveyor as shown in Fig. 2. When the discharge end of the elevator is at the desired elevation the handle 89 of the crank 88 is re-engaged with the hook to retain the elevator in adjusted position.

When it is desired to lower the elevator upon completion of the job, the handle is disengaged from the hook and the crank turned in the opposite direction to pay out the cable so that the tubular housing of the elevator returns to its engagement with the seat 68, after which the clamp 69 is applied to permit transportation of the elevator to another job site.

If desired, the auger extension 44 may be connected with the projecting end of the shaft l2 through the universal joint 43 and theauger extension laid on a pile of material so as to move the material toward the inlet of the main auger. In this way the entire pile may be moved without shifting the elevator or without shoveling of the material onto the exposed end of the screw.

From the foregoing it is obvious that I have provided an elevator of the auger type that is of simple construction and which is readily adaptable to various positions in which it may be used. If a longer length elevator is required, additional sections may be connected between the flanges 5 and 6 with the added auger sections which are rotatably mounted in the tubular housing sections.
